Patent number: 11970732Abstract: The present invention relates to a method for determining the DNA quality of a biological sample and, more specifically, to a method for determining the DNA quality of a biological sample by performing a quantitative polymerase chain reaction (PCR) using primers capable of amplifying a target gene, a method for preparing the primers used in the method, and a method for standardizing the amount of detected target gene mutation by using the determined DNA quality. The method of the present invention enables objective evaluation of the DNA quality of a biological sample used in gene analysis and the presentation of objective results on the expression ratio of a gene mutation, thereby providing reliable information in the fields of clinical research and companion diagnosis.Type: GrantFiled: April 4, 2018Date of Patent: April 30, 2024Assignees: GENCURIX INC., LOGONE BIO CONVERGENCE RESEARCH FOUNDATIONInventors: Young Kee Shin, Jin Ju Kim, Sung Su Kim, Hyun Jeung Choi, Young Ho Moon, Myung Sun Kim, Jee Eun Kim

Patent number: 10964511Abstract: A semiconductor manufacturing device includes a plasma chamber, a source power supply, and first and second bias power supplies. The source power supply applies a first source voltage to the plasma chamber at a first time and a second source voltage to the plasma chamber at a second time. The first bias power supply applies a first turn-on voltage to the plasma chamber at the first time and a first turn-off voltage to the plasma chamber at the second time. The second bias power supply applies a second turn-off voltage to the plasma chamber at the first time and a second turn-on voltage to the plasma chamber at the second time. The plasma chamber forms plasmas of different conditions from a gas mixture in the plasma chamber based on the source, turn-on, and turn-off voltages.Type: GrantFiled: January 8, 2018Date of Patent: March 30, 2021Assignee: Samsung Electronics Co., Ltd.Inventors: Seung Bo Shim, Myung Sun Choi, Nam Jun Kang, Doug Yong Sung, Sang Min Jeong, Peter Byung H Han

Publication number: 20160001037Abstract: A urinary catheter system includes a catheter, a sheath, an enclosure and a plug. The catheter has distal and proximal ends. The sheath is slidable along the catheter between first and second positions. The enclosure encloses a majority of the catheter and includes a bottom member, a top member, an outer peripheral wall defining an outer hole to allow advancement of the distal end, and an inner peripheral wall defining an inner hole, where the catheter is extendable through the inner hole. Rotating the top or bottom member relative to the other member causes the catheter to wind within the enclosure. The plug can seal the proximal end to block liquid flow, and a user can disengage the plug to allow liquid flow.Type: ApplicationFiled: September 17, 2015Publication date: January 7, 2016Inventors: Daniel Wei-Chen Hong, Myung Sun Choi, Katherine Muterspaugh Steele, David Philip Janka, Sean Kshitij Mehra, Naama Stauber

Publication number: 20080144770Abstract: A radiotherapy system capable of compensating for displacement according to the breathing of a patient, and a method for controlling the same are disclosed. The method includes the steps of: a) irradiating an affected part of the patient who lies on a moving phantom which compensates for displacement of the irradiated part according to breathing of the patient; b) measuring a distance from the irradiated part of the patient to each of ultrasonic sensors using ultrasound; c) extracting displacement of the irradiated part of the patient on the basis of the measured distance; d) generating displacement-compensation information for compensating for the extracted displacement of the irradiated part; and e) moving the moving phantom on the basis of the displacement-compensation information, and compensating for the displacement of the irradiated part. The radiotherapy system acquires the displacement according to the breathing of a patient using an ultrasonic sensor, and adjusts the location of a moving phantom (i.Type: ApplicationFiled: December 6, 2005Publication date: June 19, 2008Inventors: Suk Lee, Chul Yong Kim, Dae Sik Yang, Myung Sun Choi
